The given solution is 1.22 M, which is greater than the solubility (the maximum possible solute at a temperature that could be kept into solution, without precipitation).

Hence the 1.22 M nSO4 solution is supersaturated. Some amount of solid MnSO4 is expected to be thrown out of this solution in the form of precipitate to bring down the solute concentration a maximum of 0.463576 M, at 20ᵒC.
